Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, Volume 82, Issue 8, Page 7526-7534, August 2026.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Corn rootworm (Coleoptera: Chrysomelidae) emergence patterns, survival, and injury in blended refuges and pure stands of short‐stature corn and tall corn

Pest Management Science, Volume 82, Issue 8, Page 7645-7654, August 2026.
Graphical Abstract Text: This study compared corn rootworm (Diabrotica spp.) emergence patterns and injury between short‐stature corn and tall corn to help inform corn rootworm management strategies in short‐stature corn Abstract BACKGROUND Short‐stature corn became commercially available in the United States in 2025 and has several desirable qualities

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Polytropic Index and Thermodynamic Behavior of the Central Plasma Sheet Near Lunar Distances

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract In addition to making near‐Earth observations, the THEMIS/ARTEMIS mission is uniquely positioned at lunar distance, in the deep magnetotail, reaching distances of 60 RE ${R}_{E}$ and further. This vantage point allows ARTEMIS to access the plasma sheet and measure entropy evolution across convective channels, plasma flow gradients ...

Flushing of Subsurface Soil Nitrate as the Primary Cause of Increased Stream Nitrate During Storm Events

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The export flux of nitrate from forested catchments via streams typically increases during storms due to simultaneous increases in the nitrate concentration and flow rate. Potential nitrate sources responsible for this increase include rainwater and soil nitrate.
